Abstract: A display method for displaying a workflow system composed of a plurality of discrete Boxes each associated with a document process and linked in a predetermined order. The workflow is defined for causing the processes to be sequentially executed. The workflow is displayed using icons representing the Boxes. If execution of the associated process has been completed, an icon representing a corresponding Box is overlaid with oblique lines. If execution of the associated process is currently in process, an icon representing a corresponding Box is overlaid with a graphical representation of a sand timer.

Abstract: A document processor includes a plurality of Boxes. Each Box is capable of document management and associated with a process to be executed on a document. The sequence of the Boxes is defined in link information. The document processor passes a document from one Box to another in the defined sequence to cause the associated processes to be sequentially executed on the document.

Abstract: A device driver customizing method that is performed when a second driver is installed in an information processing device in which one or more first drivers each for controlling an image processing device have been already installed, the driver customizing method comprising: a searching step of comparing items included in first configuration data of any of the first drivers, which have been already configured by a user, with items included in second configuration data of the second driver, which are to be newly configured by the user, and thereby searching the first configuration data for an item corresponding to one of the items included in the second configuration data; and a configuration step of configuring the one of the items included in the second configuration data to have a same value as a value given to the corresponding item, if the corresponding item has been found by the searching step.

Abstract: An optical communication apparatus comprises an optical transmitter (1) which emits light signals corresponding to external electric signals (11) using light emitted from a short-wavelength light-emitting element (14) such as a yellow light-emitting diode of maximum wavelength in a range of 560–590 nm or a green light-emitting diode of maximum wavelength in a range of 490–550 nm; a plastic fiber (2) including a methacrylate polymer core free from benzene rings and having one end connected optically with the short-wavelength light-emitting element (14), the core containing less than 5 ppm free sulfur; and an optical receiver (3) having a photodetector element (31) connected optically with the other end of the plastic fiber (2) and adapted to producing an output electric signal (35) in accordance with the output from the photodetector element (31).

Abstract: A material distribution apparatus includes a storage area for storing materials, a storage area for storing conference schedule information that indicates persons to whom the material is permissible to be distributed, a user ID input portion for entering a user ID of a person who wants the material, a distribution permission decision portion for deciding whether the material is permissible or not to be distributed to the person who wants the material by comparing the entered user ID with the conference schedule information, and a material print control portion for printing the material on paper when it is decided that the material is permissible to be distributed.

Abstract: A data sending apparatus, on sending data to a receiving apparatus, searches its storage for a transmission method to the receiving apparatus. After sending data to the receiving apparatus, the sending apparatus receives from the receiving apparatus a transmission result including a transmission condition and capabilities of the receiving apparatus. When an error occurs during the data transmission, the sending apparatus reads the communication and processing capabilities of the receiving apparatus from the transmission result, and resends the data by a transmission method in accordance with the receiving apparatus. It then acquires the transmission result and stores the same in the storage.

Abstract: A data processing apparatus has a first controller which specifies an output mode for image data to be processed and a second controller which determines whether the image data is stored in a memory or not based on the output mode specified by the first controller.

Abstract: A plastic optical fiber includes having a first core, a second core having a different refractive index from the first core, disposed concentrically on the outside of the first core, and a clad disposed concentrically on the outside of the second core, wherein a ratio X (r1/r2) of a first core radius r1 to a second core radius r2 and a ratio Y (n2/n1) of a refractive index difference n2 between the second core and the clad to a refactive index difference n1 between the first core and the clad are in a range that satisfies the expressions Y≧−1.134X+1.0518 (1), and X≦−1.4842Y2+1.1097Y+0.7097 (2), and provided that Y<0.4 or X≧0.76 and that coordinate pairs X=0.8 and Y=0.35 as well as X=0.8 and Y=0.45 are excluded.
